MACHINE FOR PREPARING WELTS.

Specification of Letters Patent.

Patented Feb. 2, 11915.

To all whom it may concern:

Be it known that I, THOMAS H. SEELY, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Preparing Nelts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for preparing welts.

The welt, as supplied to the shoe manufacturer, usually comes in a rolled strip which has both of its surfaces plain and its edges cut square. To prepare the weltstrip for use in the sewing machines which attach the welt to the lasted upper and insole, it is usual to pass the welt strip through a welt preparing machine in which knives are arranged to cut a groove in the surface of the welt strip to receive the line of stitches which attaches the welt to the lasted insole and upper and to bevel oneedge of the welt strip so that it lies more smoothly against the upper when it is sewn in place. In power driven machines for preparing welts, a feed roll is usually placed beyond the grooving and beveling knives for pulling the welt past the knives. In hand machines, the welt is seized by the operator and pulled past the knives. This necessitates, in either case, that when a fresh roll of welt is to be prepared, a sutiicient amount of welt varying from a few inches to a foot must be left in front of the knives for the feed roll to act upon or for the hand to seize so that the remainder of the welt strip may be pulled past the knives. If the welt is inserted endwise into the machine, the knives must be held out of contact with the welt until a sufficient amount of welt is slipped through the machine to be grasped to pull the welt by the knives when they are brought into cutting engagement with the welt. If the welt is slipped sidewise into the machine, as is done in the machines known to the trade as the Goodyear welt grooving and beveling machines, the extreme end of the welt cannot be placed under-the knives,'but a length must be left su'l'licicntto be grasped to pull the rest of the welt strip :pastthe knives. The result is that, in welt preparmg machines as hitherto constructed, a length of welt on the forward end of every roll of welt strip is not cut by the grooving and beveling knives,so that there is a waste of a number of inches of welting on every roll which is prepared by the'machine.

One object of the present invention is to produce a welt preparing machine in which it is possible to prepare the entire length of the welt strip and thus save the forward end of the welt strip which has hitherto been wasted.

lVith the above object in view, the welt cutting knives are arranged to cut the welt strip when the welt strip is passed through the machine in either direction. In preparing the welt strip, the forward end of the welt strip is first inserted in the machine and then drawn backward to prepare the length which has been hitherto Wasted, and then the welt strip is re-inserted in the machine and the prepared-end of the strip used to be grasped by the means which pulls the welt strip past the knives.

In addition to the feature of invention above referred to, the present invention also consists of certain devices, combinations and arrangements of parts, particularly improvements in the construction of the knife carriers and the welt positioning gages, hereinafter described and claimed, the ad vantages of which will be obvious to those skilled in the art from the following de scription.

Referring to the drawings which illustrate the preferred embodiment of the pres ent invention ;'Figure 1 is a front elevation of the head of the welt preparing machine; Fig. 2 is anelevation of the right hand side of the head of the machine; Fig. 3 is'a plan view of the head of the machine; Fig. 4i is a detail view showing the means for disen gaging the presser foot and side gage from the welt; Fig. 5 is a vertical section through the welt, the work table and the presser foot carrier; Fig. 6 is a plan view of the work table; Fig. '7 is a perspective View of the beveling knife carrier; and Fig. 8 is a perspective view of the beveling knife.

The preferred embodiment illustrated in the drawings is described as follows: The welt stripZ which is to be prepared is drawn over a work table 4 by means of the two feed rolls 6 and 8. The work table 1 is secured to a bracket 5 on the machine frame by means of the bolt 7. The means which cooperate with the welt supporting table to guide the welt strip past the grooving knife 10 and the beveling knife 12' comprise a presser foot 14-, a rear side gage 16 which is formed on the presser foot and which is fixed in position laterally of the welt strip, and a front side gage 18 which is adapted to bear loosely against the front edge of the welt and is adjustable laterally of the welt strip. The presser foot 14 consists of a plate of about the same length as the work table, the right hand end of which holds the welt against the beveling knife 12, and the left hand end of which is provided with a notch 20 cut in from its front face and extending over the top of the welt. This notch is of a V-shape, the wide part of the notch opening upward and the narrow part of the notch opening onto the top of the welt. This notch is provided for the grooving knife 10 to extend through. The fixed side gage 16 is formed by a downwardly projecting flange at the back of the presser foot which acts as the supporting connection for the part of the presser foot which lies to the left of the groove 20. The movable side gage 18 consists of a flat plate arranged to slide laterally over the front of the top surface of the work table. The side gage plate 18 is secured to the upper edge of an adjustable block 22. The block 22 is mounted on the forward end of a plunger 21- which is mounted to slide through the work table. A helical spring 26 encircles the rear end of the plunger 2% between a collar 28 and the back of the work table and tends to draw the side gage 18 against the edge of the welt. An adjusting screw 30 is threaded in the block 22 to engage the front of the work table and acts as an adjustable stop for the side gage so that the position of the side gage 18 can be adjusted laterally of the welt. It is to be noted that the movement of the side gage 18 against the welt is limited by the screw 30 so that the side gage may be adjusted to bear loosely against the welt and have no tendency to compress the welt sidewise and cause the welt to buckle transversely.

The presser foot 14: is secured by means of a clamping screw 32 to a sliding carrier 34 which is received in a vertically extending groove in the machine frame and is held in place by the plate 36. A helical spring 38 presses upward on a yoke 40 pivoted at 42 to the head of the machine, which in turn presses down against the knife carrier which is mounted in the presser foot, as will be hereinafter described. The spring 38 therefore tends to hold the presser foot against the upper surface of the welt strip. Manually operable means are provided for removing the side gage 18 and the presser foot 14 relatively to the work table to permit the insertion or removal of a welt strip. Since the space in front of the presser foot 1% and above the side gage 18 is unobstructed when the side gage 18 is drawn forward and the presser foot is lifted, a clear space is left for the welt strip to be slipped from the front of the machine and sidewise of itself under the presser foot 1e and laid on the work table 1. The means for removing the side gage and presser foot relatively to the work table comprise a lever 4 1 pivoted at d6 to the machine frame and bearing a striker 18 adapted to contact with the rear end of the side gage plunger 24, and a cam roll 50 adapted to bear against a cam face formed on a bell crank lever 52 which in turn acts to raise the presser foot. The cam surface on the lever 52 is formed with 'a rise 5% and a dwell 56 arranged so that when the cam roll 50 is moved downwardly to the right, as viewed in Fig. 4, it first acts to raise the lever 52. After the roll 50 has passed over the rise 5 1, it runs on to the dwell 56 so that the presser foot is held up but isgiven no further upward movement. The motion of the cam lever 52 is transmitted to the presser foot through the arm 58 which contacts under a stop shoulder 60 on the presser foot carrier. The lever 52 is pivoted to the frame at 62 and an eccentric adjustment is provided so that the lever 52 may be moved in position relatively to the cam roll 50 and the stop shoulder 60 so that the presser foot can be liftedmore or less. The timing of the cam is such that the cam roll 50 is about to pass onto the dwell 56 when the striker i=8 is brought into contact with the rear end of the plunger 24. The result is that the presser foot 14: is lifted before the side gage 18 is moved, and when the lever 14 is allowed to move to the left, as viewed in Fig. 4:, and the springs 26 and 38 bring the side gage 18 and presser foot 14 into engagement with a welt strip, the side gage 18 is brought against the Welt strip before the presser foot so that the welt strip is positioned laterally on the work table before the presser foot is brought against it. The welt is thus positioned beneath the grooving knife before the presser foot and grooving knife come down against the work to press the welt against the work table. The grooving knife 10 therefore begins to make its out in the correct position laterally of the welt. Since the stop screw 30 limits the movement of the gage 18 over the welt table, there will be no tendency for the welt to buckle transversely so that there is no necessity for the presser foot to be brought into engagement with the welt before the welt is positioned between the back side gage 16 and the front side gage 18.

The lever 44 is arranged to .beactuated' to disengage the side gage and-presser foot at the will of the operator bymeans ofa rod 64 which is connected at 66 to'the lever 44 and runs to a treadle atthe base. of the machine. Therod 64 is normally held elevated by means of a spring 65. The rod 64 also acts to separate the lower feed roll 8 from the upper feed roll 6 at thesame time that the side gage 18 and the presser foot 14 are disengaged from the welt strip. The lower feed roll 8 is mounted in a vertically sliding box 68 and is normally pressed into engagement with the upper feed roll by means of the spring 70. The connections by means of which the depression of the rod 64 lowers the feed roll 8 comprise a lever72, a link 74, a lever 7 6 and a rod 78 depending from the journal box 68 and bearing adjustable nuts 80. The arrangement of the treadle and connections for separating the feed rolls are substantially the same as that disclosed in the patent to Charles P. Stanbon for a welt preparing machi11e,.No. 966,484, granted August 9, 1910.

The feed rolls 6 and 8 are driven in the direction indicated by the arrows by means of a vertical driving shaft 82 which bears a spiral gear 84 which meshes with a spiral gear 86 on the shaft which drivesthe upper feed roll 6. The shaft which drives the lower feed roll 8 carries a gear wheel 90 which meshes with a gear wheel 88 on the shaft of the upper feed roll, the arrangement of parts being similar to that of the above mentioned Stanbon patent.

The grooving knife 10 is carried by the presser foot carrier so that it is raised and lowered with the presser foot. The knife 10 is a U-shaped knife clamped by means of a plate 92 to a head 94 on the lower end of a knife carrying shaft 96. The knife 10 is inclined at an angle of about 30 to the surface of the welt. The knife carrier 96 is journaled in a frame 98. A head 100 is secured to the upper end of the j ournaled carrier 96 and allows the carrier 96 to turn but not to slide in the frame 98. A handle 102 is provided on tie head 100 to turn the knife carrier 96. A groove is formed across the top of the head 100 and receives a rib 10ion the end of the spring pressed yoke piece 40. The groove and rib act to hold the knife and knife carrier in two positions 180 apart. The pressure of the yoke piece 40 against the head 100 is transmitted through the frame 98 to the presser foot carrier 84 and acts to hold the presser foot against the surface of the work. The frame 98 is provided with a lateral projection 106 which is bored vertically and screw-threaded to receive a sleeve 108. The sleeve 108 is fitted in a recess in the presser foot carrier 84 between shoulders 112 and 114 and is held by means of a stud 110 which extends vertically through the carrier 34 so that it can turn but cannot slide relatively to the presser foot carrier. The sleeve 108 is providedwith acapstan head 116 wherebythe sleeve 108 can be turned and the position of the grooving knife 10 be adjusted relatively to. the presser. foot 14 so that the knife can be made to groove thewelt to the. depth desired. Means are provided for turning the frame 98 about the axis of the pin 110 as a pivot to adjust the position of the. grooving knife; 10 laterally of the welt strip. This adjusting means comprises a laterally extending-fin 118 on the upper part of the side of the'frame 98' and two adjusting nuts 120 and 122 mounted on a screw 124, which is screwed at 126 into the presser foot carrier The turning of the nuts 120 and 122 along the screw 124 swings the frame 98 about the axis of the pin 110 and so adjusts the knife 10 relatively to the back gage 16 and hence laterally of the welt. Alock nut 128 is provided to clamp the adjusting nut 122 in place and thus lock the adjustment. In adjusting the knife 10 relatively to the presser foot, the nuts 120 and 122 are loosened so that the fin 118 can move up and down. Then the capstan head 116 is turned to give the vertical adjustment to the grooving knife, after which the nuts 120 and 122 are adjusted to give the lateral adjustment to the grooving knife. Then the lock nut 128 is turned in place, thus holding the finv 118 in clamped position between the nuts 120 and 122 so that the frame 98 can neither move vertically nor laterally- The knife 12 which bevels the edge of the welt is shown in Fig. 8. This knife has a square shank portion 182 and a triangular blade portion 184. The sharp edges of the triangular portion 134 form two oppositely directed cutting knives for beveling the edge of the welt. The beveling knife is mounted in a knife carrier block 136 and is clamped in. place by a screw 138 passing through a hole in the knife and threaded at 140 in the block 136. Slots 142 and 144 are formed across opposite faces of the knife carrier 136 to provide downwardly extending passages through which the material cut from the welt strip by the beveling knife may fall. The knife carrier 136 is held in a slot 148 cut in the forward edge of the right hand end of the work table and extending back beyond the position of the welt. The work table 4 and the bracket 5 of the machine frame form the left side of this slot, while the right side of the slot is formed in part by the work table 4 and in part by an L-shaped block 150. The L-shaped block 150 has an upwardly extending portion 152 which is splined into the rear side of the work support and is clamped thereto by a bolt 154. A screw 156 screw-threaded in the work table and having a capstan head 158 fitted into a recess in the side of the block 150 affords provision for adjusting the block vertically with relation to the work table. The block 150 also has a circular rib 164 which engages in a slot 146 of the knife carrier136. The rib 16st and cooperating slot 1&6 are struck about a point at the rear edge of the welt as a center so that when the knife carrier 136 is turned, the angle of the bevel is changed, but the depth to which the bevel is cut is unchanged. A clamping screw 166 screwthreaded at 168 in the knife carrier 136 and passing through a curved slot 17 0 in the block 150 clamps the knife carrier 136 in adjusted angular position. The adjustment of the screw 156 raises or lowers the block 150 together with the knife carrier l36and beveling knife 12 so that the depth to which the bevel is cut may be varied.

The operation of the machine is as follows: With the grooving knife in the position illustrated in Fig. 5, the rod 64 is depressed by means of the treadle and the side gage 18 and presser foot 1 1 are moved so that the welt strip can be slipped sidewise into the front of the machine and onto the work table. The end of the roll of welting is thus slipped in, leaving several inches or a foot or more of welt projecting to the left of the machine. Then the operator grasps the welt strip at the right of the machine and pulls the welt backward out of the machine. The grooving knife 10 acts to cut a groove in the top of the welt and the left hand edge of the beveling knife 12 acts to bevel the edge of the welt when the welt is pulled backward. Then the handle 102 is grasped and the grooving knife 10 turned to the position illustrated in Fig. 1, after which the rod 64: is again depressed by means of the treadle and the end of the welt strip is again inserted into the machine from the front. The portion of the welt which has been grooved and beveled lies on the work table and a sufficient length of welt extends to the left of the work table so that it can be grasped between the feed rolls 6 and 8. Then the trea dle is released allowing the side gage 18 to first position the welt on the work table and then the presser foot 14 to come down and hold the work against the work table. The feed rolls are then started and the welt strip is pulled through the machine. The amount of welt which is grooved and beveled by being drawn backward through the machine will depend upon the choice of the operator. The operator can bevel a sufficient length of welt to extend from the work table to the feed roll and once or twice around the winding reel, in which case after the welt is re-inserted in the ma chine, nothing further need be done. Or the operator can bevel off a few inches of welt sufficient to extend from the work table between the feed rolls and then after starting the machine wind the end of the welt around the winding reel. By the use of the present invention, from several inches to a foot of welt can be saved on every roll of welting which is run through the grooving and beveling machine. While the grooving knife is shown as a knife having a single cutting edge and made reversible, and the beveling knife is shown as a single knife having two cutting edges, other forms or arrangements of knives may be used within the purview of the invention as defined in the claims.
